3800 Syp's car

[imported_Ron Vogel]

Ryan came by today. We put in a gutted cat to drop his boost a little, and fixed a few little things.

Took the car out for a scan. MAP Kpa topped out at 139 during WOT. Saw 0 KR (until he let off, then a blip of 2 degrees). The spark table I made for the car is closely tied to boost, so less boost + more timing.

During WOT we saw 22.5 degrees, I was pretty surprised we could get that much w/o KR. 02's stayed steady at .933mv.
Gotta love a stock pullied car with headers!

Ron were you able to mess around with my trans tables? I still need to come see you cause i'm still running lean. And for some reason when i hit 126mph my boost gauge on my DIC just goes up and down and i cant go pass that mph.

Oh, BTW...Congrats Syp.

So am I to assume that the cat is what was causing some of the false knock after this latest motor was put in? I don't know what has been up with it besides having a "perfect Ron Vogel tune"

Speaking of limiters, 130mph is it for me on the DHP.. atleast its better then the 108 one on the stock cpu.

ACtualyl... ron can explain it better... There should be a Vac line connected to 3 spots....

BBV
EVAP
and MAP

i only had it connected at the BBV and EVAP... thus running pig LEAN up top

I was a 3rd wheel. I hope you guys didn't mind me randomly showing up. I was bored and had some time to kill.

It was nice shootin the shit for a bit guys!!!

In 2 weeks I'm buying S&S headersfrom w-body store. I'm excited I got a big raise about 2 weeks ago. About $15k more a year. In about a month I'm going to order the stage 2 IC. I'm not messing around anymore.

Oh shit!

 

[Sinister Drag Designs]

damn thats pretty nice. with the money you plan on spending,why not go turbo?
i mean after installs, and you ssic for sale along with misc. stuff you probly have you can get a base kit, and take advantage of your rockers and powertuner you have.
good luck either way

 

[GTPPWR]

[nitrous]

since when does dhp put speed limiters on their pcms? my intense pcm has been up to 148+ mph

 

[SaturdaysGS]

They dont, I have a feeling it might be a catalyist overtemp protection thing kicking in.

 

[syP]

chop it off.. haha

That is what it is. Our early regal units didn't have that adjusted as we didn't notice that the factory went from 800 to 500 on that setting, lol. We did make a post a long time ago about swapping out units to fix that.

Mistakes happen, at least it wasn't a piston popping type mistake.

Ron, (or Charles, or Ryan), Can one of you explain this to me? Ryan said in a diff post (I think on clubGP) that since the BBV and FPR was not hooked up to the LIM and MAP that the PCM was not commanding extra fuel for the boost, but the PCM was going into a "dump fuel" mode where it was just adding a bunch of fuel. Did I understand this correctly, or did I misread it.

I found the quote from clubgp

From me not having that last connection, i would be running LEAN AS HELL up top... Ron Vogel can explain it better... but it has some sort of "DUMP A SHIT LOAD OF FUEL" mode when you get in the upper RPMS.

 

[syP]

ya you best let ron explain it

You fuel pressure regulator increases the psi to the injectors as you increase boost. Since his fpr wasnt hooked up to a boost line, the pressure wasnt being increased. The fuel injectors didnt know this, so they just opened like normal, with the assumption the the fuel pressure had been increased. However, since it wasnt increased, less fuel was getting through the injector. So he was running lean up top...and rich during cruise/idle. The only time he had a good mixture was the microsecond that he was at 0 vacuum/boost.
